There are times when a directory needs watched. For reasons of its own, a program may need to know when a file is deleted, updated or renamed. If .NET is involved, this is a trivial task. Create an instance of the FileSystemWatcher; set some properties, and the task is completed. If a non .NET solution is required (and regardless of the hype, some people haven't embraced .NET in all of its glory.), the ReadDirectoryChangesW function must be used, however the documentation for ReadDirectoryChangesW is sketchy at best.

"If a non .NET solution is required the ReadDirectoryChangesW function must be used"
That statement is false.
There are other Win 32 API calls that can accomplish the same thing (FindFirstChangeNotification).
Francois Piette wrote a Delphi component 7 years ago that accomplishes the same thing.
